pertains to ejected-bobbin receivers for bobbin changing looms, and moreparticularly relates to such receivers comprising a receptacle aprontherein.

having a bobbin receiving Ejected-bobbin receivers of the type to whichmy invention applies commonly comprise a suitable receptacle, usually acan, which is positioned beneath the battery of a bobbin changing loomfor receiving the empty bobbins which are ejected from the loom shuttle.

The bobbins are ejected with such force that they may be splintered orotherwise damaged if they strike either the walls of the receptacle orthe bobbins accumulated in the receptacle.

This damage to the bobbins is particularly objectionable when weavingwith rayon filling.

It has been proposed to prevent the aforementioned damage to the bobbinsby providing the receptacle with a fabric apron for receiving andcushioning the impact of the ejected bobbins,

and several constructions for purpose have been accomplishing thisproposed. However, such prior proposed constructions have not beensatisfactory and have not been used commercially to any appreciableextent. Objections to said proposed constructions are that they areexpensive, require alteration of the receptacle to permit theirinstallation, and seriously hamper the operation of emptying thereceptacle.

A principal object of the present invention is to provide anejected-bobbin receiver including a receptacle as aforesaid, a

apron comprising a bobbin receiving frame covered with fabric forreceiving the impact of ejected bobbins, and suitable means fordetachably securing only the upper edge of the apron top thereof, withthe apron tacle adjacent the extending downwardly the receptacle;whereby such constructed, may

cans, and may be readily depensively to existing bobbin to the front ofthe recepand rearwardly within apron may be inexbe readily attachedtached from such cans when the cans are to be emptied.

The foregoing and other objects of the invention are accomplished in theconstruction illustrated on the accompanying drawing, of which:

Fig. l is a view in perspective of part of a bobbin changing loom havingthe preferred embodiment of my improved bobbin receiving receptacleassociated therewith;

Fig. 2 is a View in elevation of said receptacle;

Fig. 3 is a side view of the same; and

Fig. i is a View of the improved bobbin receiving apron of Figs. l3,detached from the receptacle.

The loom shown on the drawing is generally of usual construction not ofthe present invention, and is accordingly but fragmentarily illus- 5trated. The parts shown include a right hand loom side i, the breastbeam 2 at the front of the loom, the lay it having a shuttle box t atits right hand end, the shuttle 5 having a filling supply 8 therein, theright hand picker stick l, 10 the chute or guide 3 for ejected bobbins,and transferring mechanism including the transferrer 9. It will beunderstood that the filling carriers comprise bobbins i9, and that anempty bobbin will be ejected down along the guide 8 each time a fullbobbin is transferred to the shuttle, as is well known in the art.

A receptacle for receiving the ejected bobbins NJ is placed beside theloom side i underneath the guide 8. In the particular embodiment shown,this receptacle consists of a conventional form of can 5 I having thepreferred form of my bobbin receiving apron therein. This can may besupported in proper position relative to the loom in any usual manner,not shown. The can H is a metallic receptacle having a bottom l2, frontand rear walls 53 and E i, side walls 15, and an open top. The frontwall 13 is extended upwardly and curled rearwardly to form a handle 16.

The empty bobbins it are ejected with a force which is sufficient todamage the bobbins if they are allowed to strike against the walls ofthe can I l or against other bobbins in the can. I accordingly providethe bobbin can with a bobbin receiving apron l! for receiving the impactof the ejected bobbins, the apron being of a novel construction adaptedto prevent the aforesaid damaging of the bobbins. The preferredconstruction is also such that the bobbin receiving apron may be readilyattached to existing cans such as the can i I and may be readilydetached when the can is to be emptied.

The preferred bobbin receiving apron [1 shown comprises a frame I8, afabric cover l9, and attaching hooks 2b. The frame It is preferably alight open rectangle of resilient metal, the construction being suchthat the apron is self-sustaining as to shape but sufficiently resilienttoyield under the impact of an ejected bobbin. The cover it may consistof an envelope formed from canvas or the like, slipped over the frame I8and fastened thereto as by rivets 2!. The apron thus made is ofsubstantially the same width as the bobbin can and is of the properlength to extend from the top of the front wall I3 downwardly andrearwardly within the can and terminate short of the rear wall I4.

The top horizontal edge of the apron I1 is connected to the top part ofthe front wall I3 of the can by the hooks 20. As shown, these hooks areeach attached to the frame I8 by a rivet or the like 22, theconstruction being such that the hooks are free to pivot on the rivets22. The shape of each hook 20 is such that when the apron is attached tothe can, the hook extends from its rivet 22 upwardly and outwardly ofthe can to the edge of the wall I3, thence forwardly around such edge,and thence inwardly along the wall I 3. By merely turning the hooks 20downwardly to the position shown by Fig. 4, the apron may be detachedfrom the can.

The apron I1 is attached to the bobbin receiving can only by the hooks20 located at the upper edge of the apron, the apron extendingdownwardly and rearwardly within the can I I and being otherwise freeand unsupported. Thus, the apron being resilient it yields under theimpact of an ejected bobbin and thereby catches such bobbin and allowsit to fall to the bottom of the can without damage.

Since the apron I1 is supported only by the hooks 20, it may be simplyand cheaply constructed, and may be readily attached to existing bobbincans without changing such cans in any way. Furthermore, the apron maybe quickly detached from the bobbin can when the can is to be emptied.

Having fullydisclosed the preferred embodiment of my invention, I claim:

1. An ejected-bobbin receiver for bobbin changing looms, comprising areceptacle having an open top for receiving ejected bobbins, a bobbinreceiving apron comprising a resilient frame covered with fabric, andmeans for detachably securing the top of said apron to the front of saidreceptacle with the apron extending downwardly and rearwardly withinsaid receptacle, said apron being otherwise free and unsupported wherebyit may yield under the impact of an ejected bobbin.

2. An ejected-bobbin receiver for bobbin changing looms, comprising areceptacle having an open top for receiving ejected bobbins, a bobbinreceiving apron comprising an open frame covered with fabric, and hooksat the upper edge of said apron for detachably connecting the apron tothe upper part of the front of said receptacle, said apron extendingfrom its upper edge downwardly and rearwardly within said re-' ceptaclein position to receive ejected bobbins.
